The invention relates to a grid arrangement for a plate-shaped battery electrode of an electrochemical accumulator having a frame and a grid arranged thereon, wherein the frame comprises at least one upper frame element having a connecting lug of the battery electrode disposed on its side facing away from the grid, and wherein the grid is at least formed by horizontal bars, which are bars extending substantially horizontally, and vertical bars, which are bars extending substantially vertically, wherein at least some of the vertical bars are arranged at different angles to one another in the shape of a fan. The invention further relates to an accumulator.
